To provide a pneumatic tire having furthermore improved abrasion resistance in a region having a highly-severe road surface condition.SOLUTION: A pneumatic tire includes a tread constituted of a rubber composition including a rubber constituent containing isoprene rubber as much as 50 mass% or more and below 100 mass%, and butadiene rubber as much as 50 mass% or less and over 0 mass%, and carbon black. In the pneumatic tire, dispersion of modulus (M300-M300)×100/M300, when measuring 10 points from a site on an equator on a contact area, is 20% or less.SELECTED DRAWING: None
